"Uniqueness of Aadhaar ensures that no one person can get two Aadhaars and same Aadhaar is never issued to two persons," Communications and IT Minister Ravi Shankar Prasad said in a written reply to Lok Sabha.

The minister said that every attempt is made to ensure that fake or duplicate enrolments are identified through quality checks and biometric de-duplication process, and rejected.

"In a minuscule number of cases, where a duplicate or ineligible enrolment may slip through, there are provisions for taking action against the delinquent operator/supervisor, enrolment agency; financial penalties and criminal proceedings bu lodging of FIR, besides cancellation of such Aadhaars," he said.

In a separate reply, the minister said that 354 entities have applied and have been approved for Aadhaar Authentication Services. Of these, 212 entities have set up their infrastructure system and have been provided access for use of the Aadhaar Authentication Services for their applications.

The other 142 entities are in the process of setting up their infrastructure for integration with the Aadhaar platform. Out of 212 entities availing Aadhaar Authentication Services, 134 are also providing Aadhaar based e-KYC services to the residents.
